JACOB MUSSELL, OF CALDWELL, IDAHO.

CONVEYER MECHANISM.

Lomme.

To all 'whom t may concern Be it known that I, JACOB MUssELL, a citizen of the United States, residing at Caldwell, in the county of Canyon and State of Idaho, have invented a new and useful Conveyer Mechanism, of which the following is a speciiication.

The invention relates to improvements in conveyer mechanism.

The object of the present invention is to provide for conveyer mechanism a bucket, equipped with a simple, eliicient and practical valve of inexpensive construction adapted to enable the 'bucket to lill readily with water, and capable of effectually preventing the same from leaking` while the water is being conveyed upwardly.

Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

ln the drawing -Figure 1 is a vertical sectional view of a portion of a conveyer, constructed in accordance with this invention. Figs. 2 and' 3 are sectional views of a bucket, showing the valve in its open and closed position. Fig. 4 is an enlarged sectional view of the valve. Fig. 5 is a reverse plan view of the same.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates conveyer buckets mounted on links 2 of a sprocket chain, and having open tops and provided in their bottoms 3 at suitable points with openings 4, and equipped with valves 5, which open automatically when the buckets descend in a vertical position, as illustrated at the right hand side of Fig. 1 of the drawing, to permit the buckets to fill readily and which are closed automatically by the contents of the buckets, and effectually prevent leakage of the same while the buckets are ascending in an upright position, as illustrated at the left hand side of Fig. 1 of the drawing.

Specicaton of Letters Patent.

Application led March 29, 1911.

Serial No. 617,762.

The bottom 3 of the bucket 1 is flat, and the valve 5 consists of a disk of rubber, provided in its lower face with a central recess 6 and having a flat annular face 7, surrounding the recess and adapted to fit against the inner face of the bottom 3 of the bucket around the opening 4 thereof. rlhe central recess 6 receives a substantially circular plate 8, constructed of sheet metal of a thickness substantially the same as the depth of the recess and secured to the valve by a bolt 9 and provided with a plurality of parallel guiding arms 10, extending through the bottom opening 4 and having outwardly extended terminals 11, forming lugs for engaging the outer face of the botto-m of the bucket to limit the opening movement of the valve and prevent the guiding arms from becoming disengaged from the bucket. The guiding arms, which permit the valve to open and close freely, prevent any material lateral movement of the valve and thereby maintain the annular face 7 in proper position and prevent leakage of the contents of the bucket.

The bolt 9 passes through registering perforations 12 and 13 of the valve and the sheet metal plate 8, and it has a lower threaded portion for the reception of a nut 14, and it is provided at its upper end with a head 15, arranged edgewise similar to the head of a thumb screw and seated in a recess 16 of a boss or enlargement 17, whereby the screw or bolt is held against rotary movement. The boss or enlargement surrounds the recess and provides a central thickened portion. The nut is screwed up tightly against the plate, and the central thickened portion of the rubber is compressed suificiently, and through its elasticity places the nut under suflicient tension to prevent the same from accidentally unscrewing. By this construction both the screw. and the nut are prevented from unscrewing.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A valve of the class described comprising a spider consisting of a plate and substantially L-shaped guiding arms extending from the periphery of the plate approximately at right angles thereto and forming outwardly projecting terminal lugs, a rubber disk having a recess in its underside to receive the plate of the spider, and a bolt Sil piercing the plate and the disk and provided on the underside of the plate with a nut and having a head at its upper end seated in the rubber disk.

2. A Valve of the class described including a rubber disk having a central perforation and provided in its lower tace with a recess, said disk being also provided at its upper face with a centrally arranged boss surrounding the perforation and having a recess, a spider consisting of a plate tted in the recess in the lower face of the disk and provided with depending approximately L-shaped guiding arms, a bolt passing through the perforation of the disk and piercing the plate of the spider and provided at its upper end with a head seated in the recess of the said boss, and a nut arranged on the lower end of the bolt and engaging the lower tace of the said plate.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.

JACOB MUSSELL.
